Philips Sonicare ProtectiveClean 4100 Toothbrush vs Philips Sonicare 1100 Series Toothbrush

“I’ve had the most basic rechargeable 4000 series for like 5 years now. Still works like a champ. This buzzes every 15 seconds or something, and notifies when you’re brushing too hard.”

“Buy the cheapest Sonicare that has a timer. That's all you need. Everything else is a gimmick.”
